But when you look at teams like the Jets, Bucs, and 49ers today, it's interesting to see that their biggest issues can be directly traced to what happened in 2009.

The Tampa Bay Buccaneers are the best example. This is one of the most talented teams in the NFL. They have the third best defense in the league, and their skill players at running back and wide receiver are Pro Bowl caliber. But they've been undone by quarterback play. They picked Josh Freeman 17th overall in 2009, and built their entire team under the assumption that he'd grow into the franchise QB by 2012. He never did, and now they've regressed as a franchise.

Some other teams still dealing with the fallout:

St. Louis Rams. They had to give offensive tackle Jake Long a $34 million contract this summer to replace the gaping whole left by Jason Smith. That crippled their cap space (although with Sam Bradford's contract), and now they're struggling with holes all over the field.

New York Jets. The team's mishandling of Mark Sanchez turned him into a laughingstock last year. They had to draft Geno Smith in 2013, and now they're back in a rebuilding phase four years after doing the same exact thing with Sanchez.

San Francisco 49ers. They still can't find anyone to catch the ball four years after drafting Michael Crabtree to be the No. 1 option. They've had to return to a power running game after experimenting with an up-tempo passing attack failed.

Arizona Cardinals. They have one of the worst rushing attacks in the league, and had to pick up Rashard Mendenhall (!) this offseason. They drafted Beanie Wells in 2009 under the impression that he'd be the running back for years to come.
